Application filed February 27, 1.906. Serial No. 303,210.

To @ZZ wiz/0in, it may concern:

Be it known that I, JOHN D. OLcoTT, a citizen of the United States, and resident of Norwalk, county of Huron, State of Ohio, have invented certain new and useful Improvements in Horseshoes, of which I hereby declare the following to be a full, clear, and eX- act description, such as will enable others skilled in the art to which itv appertains to make and use the same.

The invention relates to a horseshoe and casing formed of a flanged plate having one or more legs or flanges.

The objects of the invention are to provide a form of horseshoe such that hardened calks can readily be attached'thereto, and thereby a harder material can be employed out of which to form the calksv than it would be practical to weld to the shoe and hard er than the material forming the shoe, and which also can be detached from the shoe for sharp` ening and replaced without removing the shoe from the horses foot.

A further object is to form a shoe-casing to which the calks can be conveniently secured or within which a detachable treadplate can be secured to which the calks are attached.

I am aware that heretofore calks have been removably secured to horseshoes by means of screw-threaded extensions. I desire, however, to obtain a greater bearingsurface and stronger means of support, and hence greater efficiency and durability, by means of the improved form of construction embodied in this invention.

A further object of the invention is to utilize the narrow edge of the flange to form teeth for immediate use, such as employment on ice or slippery roads, which would not injure the shoe for other employment.

A further object is to form an inclosure or chamber within which toe-weights can also be attached in speeding horses in place of visible weights attached to the outside of the hoof.

A further object is to form an inner chamber in which plastic substances containing moisture or medicated foot-packs can be applied to the frog and sole and quarters of the foot of a horse with dry or crippled feet, or to give frog-pressure to the frog of the foot when necessary to contract the foot and retain the packing while the horse is being driven on the road or at work without danger of its falling out of place, and thus relieve the suffering animal from fever and distress' and shield'it from dirt and to prevent the shoe from balling with snow consequent/upon the adhesion of snow between the inner edges of the shoe and foot.

Another object is to form a channel'or r'eceptacle for a cushion to relieve theja'r upon the hoof, which is particularly greatv upon pavements or race-tracks.

This construction avoids the application of rubber directly to the foot, as is the case in the use of rubber pads covering the whole surface of the foot, as now in use,whichif left on the foot too long retard the natural growth of the hoof and cause the frog of the foot to decay, and also the cushionv is not punctured by the nails which attach the shoe to the foot and is notl in contact'with the ground, hence is more durable and less in'- j urious to the horse. It can also be renewed' at any time without removing the shoe from the foot.

The packing is also inclosed, so that it can be of any shape or elastic material. l

I accomplish these objects and obtain such` advantages as have heretofore been described or may appear hereinafter by means ofthe forms of construction and combination and arrangement of parts as are described in the following specifications, illustrated in' the pointed out in the claims.

In the accompanying drawings, Fi rure l is a plan view of a combined shoe an casing embodying the generall features of the invention. Fig. 2 is a longitudinal section therethrough, showing a plate with angular flange or leg, removable calks secured to the vertical flange, and a bottom plate and hinged door or keeper designed to receive and retain moist or medicinal substances in contact with the foot. Fig. 8 is a plan view of this plate and hinged keeper. Fig. 4 is a erspective view of one of the heel-calks. ig. 5 is a similar view of the toe-calli, and Fig. 6 is a transverse section of this shoe and casing, showing an inner tread-plate to which the calks are attached and an elastic cushion interposed between the casing-plate and the inner tread-plate. Fig. 7 is a plan view of a similar shoe and casing having two vertical anges or legs. Fig. S is a central longitudinal section therethrough. Fig. 9 is a transf verse sectionV thereof; and Fig. l() is a sideI accompanying drawings, and are specifically' elevation of a shoe and casing, showing teeth filed in the narrow edges suitable for use on ice.

In these figures, 1 is a flat plate of horseshoe form, on which the foot rests, and is provided with nail-holes 2 for securing the shoe Yto the foot in the usual way. This plate is provided with a vertical leg or flange 3 on the outer side and in Figs. 7, 8, and 9 is sho'wn with a similar inner flange L1, thus forming combined shoe and casing, as previously stated. This vertical flange forms a support for calks 5 and 6 inclosed therein, which can therefore have any amount of needful bearingsurface on the casing and can be made much larger and stronger than if attached to a thin shoe alone. One method of attaching these calks is shown in Figs. 1 and 2, 3 and 1, where the heel-calks 5 are shown provided with lateral lugs 7, which enter holes 8 in the flange. Bolts 9 are used to complete the fastening. The front or toe calk 6 is bolted to the flange by bolts 10 and is provided with a shoulder 11, on which the edge of the flange rests, so as to protect the plate 1 and hold the calk more securely.

In Figs. 6, 7, 8, and 9 an inner shoe-shaped plate 12forms the tread or calk plate, and to it the calks are attached or are formed integral therewith. This plate 12 can readily be removed, since it is only secured by pins or screws 13, inserted in the vertical flange or flanges to prevent its dropping out. The advantage of this method of `mounting the calks is found in the opportunity thus afforded for interposing a spring or cushion 15 between the outer plate 1 and inner plate 12.

The cushion can be metallic or formed of any suitable elastic substance, such as rubber, and 'will not interfere in this position with the driving of the nails in the shoe. An advantage is found in the location of the cushion between two plates, the upper one being the nail-plate, since if the nails penetrate the rubber and lower plate, as now often used, the constant compression of the rubber will lessen the distance between the foot and plate and the nails will Vwork loose or" break off.

A bottom plate 16 is shown secured in any 'suitable manner, as by screws 17, as in Figs. 1,

2, 7, 8, and 9, or between the cushion 12 and plate 1, as shown in Fig. 6. This bottom plate serves,with the casing, to form an inclosed chamber in which moist clay or medicated packing of anykind can be inclosed and kept in constant contact with the foot for any length of time. This material thus protected will retain its efficiency for some time, even if the horse is in motion.

A dooror keeper 19, hinged to the plate at 20, gives access to this chamber for packing or renewal. and also permits the clay or other packing to be continued upward around the horses heel. A turned-down extremity 21 of the hinge-strap serves to retain a strap passed about the horses hoof and keep thedoor shut.

In Figs. 1 and 3 side arms 22 engage the heel-calks and prevent the bottom plate,with door attached or'detached, from dropping down.

Fig. 10 shows how teeth 30 can be filed in thc edges of the casing for temporary use on ice or slippery floors, which can easily be resharpened on the foot, since the casing is formed of soft material.

In connection with these forms of horseshoe an expansion-spring 25 is shown inserted between the heel-calks to prevent the contraction of the outer shell of the hoof from pressing upon the frog. This spring can be of any strength or tension to suit the requirements of the condition of each foot.

Having described the invention, what I claim as new, and desire to secure by Letters Patent, is-
